Abstract: Provided in the present application are a report sending method, a terminal, a base station, an apparatus and a storage medium. The method comprises: according to an identifier of a first MRB, which is configured by a target base station for a QoS flow of a target MBS service, determining an identifier of a second MRB, which is configured by a source base station for the QoS flow of the target MBS service; and by means of a packet data convergence protocol (PDCP) entity corresponding to the identifier of the second MRB, sending, to the target base station, a PDCP state report for the QoS flow of the target MBS service. In the embodiments of the present application, by means of using a PDCP entity which has been established for a first MRB of a source base station before switching, the release and establishment processes of a PDCP entity corresponding to a second MRB are prevented from being triggered during the switching to a target base station, thereby guaranteeing lossless transmission based on a PDCP state report, and guaranteeing the reliability of data transmission.

Abstract: Embodiments of the present disclosure provide a broadcast-multicast service session transmission control method and device. The broadcast-multicast service session transmission control method performed by a user equipment (UE) includes: receiving session state information of a broadcast-multicast service session, transmitted by an access network device; and stopping monitoring a data transmission channel of the broadcast-multicast service session, in case that the session state information indicates that the broadcast-multicast service session is in a release state. Thus, in the embodiments of the present disclosure, when the MBS session is in the release state, the access network device can notify the UE in the MBS session that the MBS session is in the release state, so that the UE can no longer monitor a data transmission channel of the MBS session, thereby saving the power.

Abstract: A multimedia broadcast multicast service (MBMS) receiving method and apparatus are provided. The method includes: determining a first MBMS to be initiated; determining, according to a mapping relationship, a state instruction corresponding to the first MBMS, and the state instruction is used for instructing a terminal to receive the first MBMS in an RRC connected state or a non-RRC connected state; if the state instruction is used for instructing the terminal to receive the first MBMS in the RRC connected state, the terminal determining whether the terminal is currently in the non-RRC connected state; and if the terminal is currently in the non-RRC connected state, sending an RRC connection establishment request to a network device, and the RRC connection establishment request includes first instruction information, and the first instruction information is used for indicating that the reason for establishing the present connection is to receive an MBMS.

Abstract: This disclosure provides a terminal state processing method, a device and a medium. The method includes: in a case that a network is overloaded due to an excessive quantity of terminals receiving an MBMS service in an RRC_CONNECTED state, indicating, by a network side device, that a terminal receiving the MBMS service is to enter a specified RRC state, and/or indicating, by the network side device, a time duration for a terminal to receive the MBMS service in the specified RRC state. The terminal enters the specified RRC state in accordance with the indication, and/or receives the MBMS service in the specified RRC state during the indicated time duration.
